The controlling model was built so that the effect on the beam stress , elevation and cable tension which are caused by some important factors such as beam deadweight , cable tension error , temperature , shrinkage and creep of the concrete and so on can be analyzed to make sure how to control these important factors during the construction 本文通过建立施工控制模型，从理论上分析了各个设计参数对主梁内力、标高以及索力的影响，确定了以梁段自重、张拉索力误差、温度及混凝土收缩徐变等影响因素为重点的控制内容和方法。
The peculiar mechanical character about pumping liquid concrete is discussed . based on the supposition that the ability of transferring hydraulic pressure of liquid concrete is orthotropic and the friction forces exists between concrete and steel tube , the pressure formulas of liquid concrete and the allotting formulas of deadweight are reasoned out . a new method is brought forward for allotting deadweight of liquid concrete during simulation analysis in pumping - core - concrete construction phase , which improves the calculation precision 在探讨泵送液态混凝土的特殊的力学性质基础上，在假定液态混凝土传递压强能力为正交各向异性、混凝土与钢管壁之间的存在有摩擦力的前提下，推导出液态混凝土压强公式和自重荷载的分配公式，提出了在进行钢管内混凝土灌注过程的施工仿真分析时处理液态混凝土自重荷载分配的合理方法，从而提高施工仿真分析的计算精度。
1 sedimentation anyslys of soil under the action of deadweight ; 2 sedimentation anyslys of structure in using ; 3 endogen force anyslys of structure in using ; 4 soil remolding type anyslys ; 5 homogenous flush works anyslys ; 6 anyslys of the structure sedimentation effects of different flushing amount at the same place ; 7 anyslys of the structure sedimentation effects of different flushing places ; 8 anyslys of the structure sedimentation effects of different horizontal flushing places ; 9 anyslys of the structure sedimentation effects of different vertical flushing places ; getting the different between the endogen force of common structure and that of slant structure . the rule of stricture sedimentation and the effect of different soil remolding type were also gained 对掏土纠偏过程做了以下9个方面的分析： 1 、土体在自重作用下的沉降分析； 2 、建筑物在使用阶段的沉降分析； 3 、建筑物在使用阶段的内力分析； 4 、土体受扰动类型分析； 5 、均匀冲水施工过程分析； 6 、同一个地方冲水量大小不同对建筑物沉降影响分析； 7 、不同沉井冲水对建筑物沉降影响分析； 8 、进深不同的土层冲水对建筑物沉降影响分析； 9 、不同埋深土体冲水对建筑物沉降影响分析。
Cbsa ( curved box girder structural analysis ) is programmed by this method in the environment of visual basic 6 . 0 and it has friendly interface and visual forms for data input . it can analyze the loads including deadweight , prestressing force and temperature in curved box girder , output influence lines and load dynamically to calculate deformation and internal force 该程序采用visualbasic6 . 0编写，具有友好的界面，可视化的数据输入窗口，可以对弯箱梁桥的自重、预应力及温度荷载等进行分析，并可输出影响线，对弯梁进行动态加载，求解活载内力及变形。
Therefore , the master of a merchant ship not only should pay attention to the safety management , but also should master the knowledge of ships operation . from the angle of the ships operation , qualitatively and quantificationally analyze the operating ratio , shipping ratio , deadweight output coefficient , etc factors " rates in affecting ships revolving rate . and the thesis also probes into the problems like how to improve the deadweight output coefficient , the operating ratio , shipping ratio 并从船舶经营成本的角度对船舶经营生产成本费用在船舶生产实践中进行了初步的研究，并对如何控制提出丁建议在市场经济环境下的船舶管理人员，不仅仅是在驾船技术方面具有较高的素质和技艺，而且在生产经营和船舶管理方面也必须具备较高的管理水平和具有经济的头脑。
